推荐刚刚开始学C语言的同志们看下

#include <stdio.h>
void main()
{
	int int_a;
	float float_b;
	double double_c;

	clrscr();
	puts("Please enter a int number:");
	scanf("%d",&int_a);
	puts("Please enter a float number:");
	scanf("%f",&float_b);
	puts("Please enter a double number:");
	scanf("%lg",&double_c);

	printf("int_a = %d\n",int_a);
	printf("float_b = %f\n",float_b);
	printf("double_c = %g\n",double_c);
}
